Yes, listening to VOA or RF, or DW in 70-s (which is what I did, and btw they had Ali-Spinks results, which is where I found out it from, before they showed it on the Soviet TV) was not as dangerous: if found out, you'd be on the KGB sh**t list, and possibly have troubles with work etc etc, but not go to prison for it.
Plus they jammed the signals, so you could hear that hum all the time.

But during Stalin you could go to jail for that. And during the war they made everyone turn them in altogether, and the punishment for non-compliance was death, and then whoever kept the radios would face the same from tehj occupying German forces, and this is why SVD is rarer than hen's teeth. And if you think RCA140 is expensivem, SVD commands about 4-8 times the price in good American dollars today.
